multicellular evolution

Multicellular evolution refers to the process by which single-celled organisms advanced into complex organisms made up of many cells. This transformation likely began about a billion years ago, as individual cells started grouping together, sharing resources, and coordinating functions. Over time, these cells specialized for different roles—like those forming muscles or nerves—enabling more complex and efficient living forms. This evolution paved the way for diverse life forms, from plants to animals, allowing them to adapt better to their environments and increasing their chances of survival.
